Another adorable royal-baby moment came on Sunday, when Sweden's Princess Leonore was baptized in Stockholm. Princess Leonore, Duchess of Gotland, is the daughter of Princess Madeleine and Christopher O'Neill, a New York banker, and she was born this past February. Her baptism ceremony took place in the Drottningholm Palace church with 150 guests in attendance. Among the guests were other members of the royal family, including King Carl Gustaf, Queen Silvia, Crown Princess Victoria, little Princess Estelle, and the handsome Prince Carl Philip, who was joined by model Sofia Hellqvist. Outside the church, the royal family posed for pictures, and at one point, attention fell on a member of the royal guard who fainted during the guests' arrival. Check out all the must-see snaps from Princess Leonore's baptism, and then take a look back at Prince George's christening!
